One large triangular craft with one dim light on each end and a smaller craft which looked like a helicopter. Both of which made no noise.

I was traveling North on Highway 65 when I noticed a very large triangular shaped craft and a smaller craft which crossed over the interstate traveling around 50 mph. The larger craft had 3 small dim lights at each end of the triangular shape and a larger red light on one side. The smaller craft had many lights and looked more like a helicopter. By the time I had reached the part of the interstate where they had crossed, they were over the trees heading southeast. I stopped my car on the side of the road, got out, and continued to watch these two craft continue to travel very slowly. I heard no noise at all from these two craft. I got back in my car and continued to travel North. About 5 minutes later I saw about 6 military helicopters cross the interstate in the opposite direction. I knew they were helicopters by the very loud sound their blades made. This all happened about 20 or 30 miles south of Montgomery, AL at 9:15 pm.
